.@RandomTBush There's also BabyMario, EGadd, GoldenRetri, Mashiko, Muncher, Nabbit, Tetris and ...WindowsLogo? What?!?— Random Talking Bush (@RandomTBush) September 25, 2015
A few of those make a lot of sense, but the Tetris one is a bit of a stretch...and the Windows logo is just plain weird. I guess we'll have to sit back and wait to see if Nintendo actually adds this content in a future update.
